Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their notable holding force, neodymium magnets have these key benefits:
- They do not lose their strength nearly ten years – the decrease of strength is only ~1% (according to tests),
- They show strong resistance to demagnetization from external field exposure,
- The use of a mirror-like silver surface provides a refined finish,
- They possess significant magnetic force measurable at the magnet’s surface,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- Thanks to the freedom in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which increases their application range,
- Important function in new technology industries – they are utilized in computer drives, electric motors, clinical machines as well as sophisticated instruments,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to shocks, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage and strengthens its overall robustness,
- They lose magnetic force at elevated temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- They rust in a humid environment. If exposed to rain, we recommend using encapsulated magnets, such as those made of plastic,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is difficult,
- Health risk linked to microscopic shards may arise, when consumed by mistake, which is notable in the health of young users. It should also be noted that small elements from these magnets have the potential to complicate medical imaging if inside the body,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Exercise Caution with Neodymium Magnets
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets will bounce and contact together within a distance of several to around 10 cm from each other.
Neodymium magnets are noted for their fragility, which can cause them to crumble.
Neodymium magnetic are delicate as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Maintain neodymium magnets away from children.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
The magnet coating contains nickel, so be cautious if you have a nickel allergy.
Studies show a small percentage of people have allergies to certain metals, including nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Do not bring neodymium magnets close to GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are the most powerful magnets ever invented. Their power can surprise you.
